Hagflsh (Myxine glutinosa Linnaeus) Jordan and Evermann, 1895-1900, p. 7. Description.—The hag, like the lamprey, lacks paired fins and fin rays. Its skeleton is wholly cartilaginous, without bones, its mouth is similarly jawless, and its skin is scaleless. It is easily recognized by its eel-like form; by its single finfold (a fold of skin, not a true fin) running right around the tail and forward on the lower surface of the body with no division

It is easily recognized by its eel-like form; by its single finfold (a fold of skin, not a true fin) running right around the tail and forward on the lower surface of the body with no division into dorsal, caudal, and anal fins; by the single gill pore on each side, just forward of the origin of the ventral finfold; by its lipless mouth, stellate in outline when closed; by the single nasal aperture at the tip of the snout; by its peculiar barbels or "tentacles," two flanking the mouth on either side and four surrounding the nostril; and by the evertible tongue studded with rows of horny rasplike "; We might also mention the series of mucus sacs on either side of the abdomen, and point out that the dorsal finfold originates two-thirds and.

Hags vary in color, perhaps to correspond with the color of the bottom. They are grayish brown or reddish gray above, variously suffused, mottled, or piebald with darker or paler gray, brown, or bluish; below they are whitish or pale gray. They grow to a length of about 1 foot to a foot and a half. General range.—Arctic seas and both coasts of the north Atlantic; south in deep waters to the latitude of Cape Fear, N. C. (33° 50' N.). Occurrence in the Gulf of Maine.—The hag is only too common in the Gulf of Maine; perhaps it is not absent from any considerable area of smooth bottom. Thus it is abundant generally off the north end of Grand Man
